Hello everyone! Welcome to advanced neurobiology!
Neuroscience is a wonderful branch of science on how our brain perceives the external world, how our brain thinks, how our brain responds to the outside of the world, and how during disease or aging the neuronal connections deteriorate. We’re trying to understand the molecular, cellular nature and the circuitry arrangement of how nervous system works.
Through this course, you'll have a comprehensive understanding of basic neuroanatomy, electral signal transduction, movement and several diseases in the nervous system.
This advanced neurobiology course is composed of 2 parts (Advanced neurobiology I and Advanced neurobiology Il). They are related to each other on the content but not on scoring or certification, so you can choose either or both. It’s recommended that you take them sequentially and it’s great if you’ve already acquired a basic understanding of biology.
Thank you for joining us!

Now click on the, [FOREIGN]. This one. It's special here. So you want to design a system, actually don't leave a blank. Supported there, right? [FOREIGN] See, this system is designed actually, you can see. The receptor field of individual neurons, they overlap. [FOREIGN] Right. [FOREIGN] protection. [FOREIGN] [FOREIGN] easy to imagine. [FOREIGN] To a sensory map. [FOREIGN]. >> Okay, good. >> [FOREIGN] >> Okay. >> [FOREIGN] >> [FOREIGN] >> [FOREIGN] Okay, okay, actually is [FOREIGN]. You can map. [FOREIGN] Okay? Yeah, this is the entire principle, right? [FOREIGN] If I use a electrode. [FOREIGN] Stimulate. [FOREIGN] You should see a spike. I think I mentioned that, right? To the action potential. You're wrong, I'll talk about action potential. This is the action potential. [FOREIGN] Now action potential sensory coding. [FOREIGN] What kind of information you want to code? Strings, okay good, and then? [FOREIGN] And then? Good, timing, it's very important. [FOREIGN] See the timing is very important. Okay strange timing and then? >> [INAUDIBLE] >> Okay petition. Of course yeah petition is the receptive field can detect depth position. Good. >> [INAUDIBLE] >> Frequency, okay, good. Also, yeah, it's important, right. I guess also, another modality. [FOREIGN] Mechanical stimulation, or chemical stimulation. [FOREIGN] modality. [FOREIGN] sensory information [FOREIGN] code [FOREIGN] code stimulus. Three very important aspects, features [FOREIGN] modality. Sensory modality. And then sensory strength. And also the timing of the stimulation. Okay, so we know right now, okay? So you have a sensory stimulation. Then you can transduce into the electric signal. And this signal, actually coded. By the frequency of the file rate, right, or the, okay, let me ask you a question. So if I give you I expect train just so that you're trying to spike? Do you want to do the spike train? [FOREIGN] No? [FOREIGN] Right? Okay, then what? [FOREIGN] Frequency [FOREIGN] possible. Okay? [FOREIGN] spike [FOREIGN] frequency [FOREIGN] So for this topic, actually of course right now we don't know the, [FOREIGN] Okay! [FOREIGN] timing [FOREIGN] frequency [FOREIGN] frequency [FOREIGN] [FOREIGN] neuron coding. [FOREIGN] frequency [FOREIGN]. To go a temporary information. [FOREIGN] Okay?
